C# 动态XtraReport在细节上为我提供了很多行间距

我正在编写一个使用Excel文件动态创建发票的程序。一切正常，除了“报告详细信息”部分显示了很多行之间的间距，最多为2'间距。我正在使用绑定标签创建线条。我已经读到，使用xrichtext可以有所帮助，但实际上没有。你能帮帮我吗

数据绑定XtraReport使用细节标注栏设置渲染每一行。设置不仅包括添加到详图标注栏的构件，还包括详图标注栏高度。若要减小行间距，请将该属性设置为较小的值。

我猜这会出现在BeforePrint方法中，对吗？您可以在XtraReport构造函数中甚至在可视化报表设计器中更改此设置。我猜这会出现在BeforePrint方法中，正确吗？您可以在XtraReport构造函数中甚至在可视化报表设计器中更改此设置。
